Serial N'o. 612,150.

My invention relates to padlocks, and more particularly to a padlockprovided with an improved form of shackle andv locking mechanismcooperating therewith.

In some situations, it is difiicult to secure a padlock provided withthe ordinary shackle,

Which is permanently secured to the case of the lock, to the parts whichareadapted to be locked together and in some cases, when the shackle ismade suiiiciently large so that it may be secured in position with ease,it will be quite loose when it is locked and an objectionable noise orrattle will result. This has been found to be true especially in the useof padlocks in connection with tire car riers upon the rear ofautomobiles, and while the form of my invention shown in the drawings isparticularly adapted tosuch use, it will be understood that theinvention is capable of broader, application, and that'the principlesthereof may be used in other relations. p J i Further, in many of thepadlocks now in use, it is only necessary to apply a moderately strongWrench to the case of the lock, and by a twisting operation, the lockmay be broken and released. Bythe present invention, the shackle isrotatably secured or locked to the case so that even if thecase isturned relatively to the shackle by means of a wrench, the lockingmechanism will not bedisturbed and the lock cannot be broken andreleased.

One object of my invention is the provision of a padlock having aletachable shackle so thatthe latter maybe inserted through the membersto beilocked together from the side thereof opposite that upon which thelock case lies. 7

Another object of my invention is to provide a padlock adapted to bedetachably as sociated with and locked to a shackle so that a number ofshackles of different form may i be used with the same look case.

and economical structure which will'be ef- "ficient in operation, whichmay be made cheaply and of such material 'that'itcannot be easilybrokenor released, by means of a saw o'r the like.

To these and other ends, the invention consists inthe novel features andcombinati a modified form of tire carrier with which a different type ofshackle is used in my improved lock; Fig. 5 is a "sectional View throughthe lock mechanism on line 5 5 of Fig. 4;

It will also be understood that my improved padlock may beused upon practically all of such tire carriers now in use, and that theparticular forms shown are merely illustrative of the va'rious uses towhich the lock be provide a padlock which consists of a simple ofpartsto be hereinafter described and put and are not to be considered asshowin-g all of the forms contemplated.

In Fig. 1 of the drawings, I have shown a tire carrier 10 upon which'ismounted a rim 11 carrying the usual inflatedtire 1 2.

The carrier 10 is provided, near its upper portion, with thelugsI-8-aiid 14: between which the rim 11 may be placed. The tirecarrier in this instance consists of a metallic rim or band of circularform which comprises somewhat more than half of a com plete circle. Tothe lower ends of the carrier are pivoted, at 15 and 16, the swinginglugs 17 and 18 which are adapted to be swung upwardly to permit thepositioning of the rim upon the carrier.

To the lugs 17 and 18 are pivoted respectively at 19 and 20 the links 21and 22 which are in turn pivoted together at 23. The link 21, as clearlyshown in Figure 3, is of channelled form in cross section and is adaptedto receive the link 22 between the walls of the channel. These links areprovided with registering openings 24 and 25 through which the shackleof the lock may be inserted to lock the parts together. It will beapparent, that when this shackle is withdrawn and the free end of thelink 21 drawn upwardly, the pivot point 23 will also be carried upwardlyacting as a toggle point which will draw inwardly and upwardly the lugs17 and 18 until these lugs no longer engage the tire rim. The tire maythen be freely removed from the carrier. It will also be obvious thatwhen the shackle of the padlock is secured in the openings 24 and 25 andthe two links locked together at this point, the structure will be rigidand the lugs 17 and 18 will be locked in position to engage the tire rimand prevent its removal from the carrier.

My improved lock is provided, in this instant, with a bolt-like shackle26, clearly shown in full lines in Figure 3. The shackle is providedwith an enlarged head 27 which is of such a size that it will not passthrough openings 24. Adjacent the end of the shackle, opposite thishead, is provided an annular recess 28, the purpose of which will bedescribed hereinafter.

The lock mechanism consists of a case 29 recessed or bored at 29 toprovide a seat to receive a cylindrical lock casing 30 containinglocking mechanism of the pin tumbler or any approved type, and in whichcasing is rotat-ably mounted the usual key plug 31. At its inner end thecylindrical casing is provided with a transverse bore 32, in which ismounted the sliding bolt 33, urged to its outward or looking position bythe spiral spring 34 mounted in the bore or recess 32 behind the bolt.

This bolt is notched at 35 and a projecting pin 36 upon the end of thekey plug is adapted to he received within this notch to operate thebolt.

The padlock case is also provided with an opening or bore 37 whichextends substantially parallel to the axis of the lock cylinder andwhich is adapted to receive the end of the shackle 26, the locking bolt33 being of such a length as to project into the bore 37 through anopening 38 in the partition 39 in the casing, and engage within theannular channel 28 to lock the shackle to the case.

The lock mechanism which secures the shackle 26 within the padlock caseis all housed within the lock casing 30 so as to provide a unitary lockmechanism which may be assembled within the casing 30 before the latteris placed in the seat 29 in the case 29, and is thereafter inserted intothis seat as a unit. In this way the structure of the padlock casing 29is greatly simplified, and at the same time a secure structure isprovided. In the lock shown, the pin tumbler mechanism 31" is of coursemounted within the case 30 prior to the insertion of the latter withinthe bore 29.

It will be apparent that when it is de sired to apply the padlock so asto secure the tire rim upon the carrier, the shackle may be insertedthrough the openings of the links 21 and 22 from one side thereof andthe lock case applied at the other side of these links, as shown inFigure 7, as when the bolt 33 is withdrawn from the channel 28, theshackle 26 may be completely detached from the lock case. It is notnecessary therefore to provide a shackle of sufficient size to embracethe two links or one which shall have a sufficient opening between theend of the shackle and lock case when the shackle is in open position sothat it may be slipped over the links. The shackle 26 may be made ofsuch a length that the head 27 upon one side and lock case 29 upon theother will lie in close juxtaposition to the sides of the link 21, sothat there will be very little likelihood of the parts to rattle.Moreover it will be apparent that lock case 29 may be freely rotatedrelatively to the shackle 26, the end of the bolt 33 turning freely inthe channel 28. Itwill, therefore, be impossible to break the lock by arelative twisting movement of the lock and shackle with a wrench, as isoften done. It would also. of course, be very dif ficult for such atwisting motion to be applied to the lock embodying the present. i11-vention as the shackle 26 turns freely in the openings 24 and 25 and asit would be difficult to grip the head 27 in a wrench or light tool, tohold it against rotation.

1 have shown in full lines in Figure 5 another form of shackle which maybe used with my improved look. This shackle consists of a U shapedmember 41, one leg of which is considerably longer than the other and isprovided with the annular recess 28 to cooperate with the lock bolt 33as has already been described. The shorter leg of this shackle 41 may beadapted to be received in the recess 42 formed in the upper side of thelock case. For this purpose, and as shown, this leg of the shackle isprovided with a reduced end 43 which is received in the recess 42. Itwill be understood that this leg of the shackle is not secured in therecess 42 in any manner and the. lock case just as in the caseof'shackle mechanism of the padlock. Its function chiefly is to preventplay or rattling of the parts and it will be apparent that when the bolt33 is withdrawn from the recess 28, the shackle 41 may be completelydetached from 26. If desired, the shackle 41 maybe used 'with the tirecarrier mechanism shown in F lgures l3, the shackle and lock case beingapplied at opposite sides of the link 21, as has already been described.7 I

The shackle 41 is particularly adapted to be used with my improved lock,however, in

connection with the form of tire carrier shown in Figures 4 and 5wherein the carrier also secured rigidly to the rear of thecar. 0 Thelink 48 is provided at its lower end with the projectinglug 51 adaptedto engagethe tire rim when in the position'shown in Fig-. ure 5 and inthis pos tion, 1t Wlll cooperate with the lugs 46 and 47 to secure therim in position. 'Ihe link 48 and the plate 50 are provided withregistcringopenings 52 and 52 and at their upper ends'with registeringnotches 53 and 58. It will be apparent that with the usual form ofpadlock shackle, it would be quite difficult to insert the end of theshackle through the openings 52 and 52,

and notches 53 and 53 to secure the link 48 to the plate 50. 1V ith myimproved form of shackle, however, it may be completely detached fromthe lock case and the shackle 41 may be placed in position to hold thelink 48 and plate 50 together and the case 29 thereafter applied to theshackle. 7

It will .be understood that when the lock is removed, the link 48 may berotated about the bolt 49 so as to move the lug. 51 to the position inwhich it will not engage the tire rim, and the rim and tire may at thattime be freely lifted from the carrier. If, however, the link 48 issecured to the plate 50 at another pointas in the case when they arelocked together as shown in Figure 5, such rotation cannot occur.Moreover, it is desirable to have the shackle of the padlock secure themembers 48 and 50 at more than one point or else the bolt 49 might beremoved and the link 48 rotated about the padlock shackle; for example,if the notches 53 and 53 were not provided to receive one of the legs ofthe shackle, or if the shackle used was in the form of the shackle 26,the bolt 49 could be removed and the link 48 rotated moved from thecarrier. When the parts are,

however, secured as shown in Figure 5, such man1pulation Wlll belmposslble.

In Figures 8 and 9, I'have shown a still further form of tire carryingmechanism with which my improved lock may be advantageously used. Inthis case the circular tire carrier 55 is provided with the fixed lugs56 and'57 and with a rigid cross bar 58. At the lower part of thecarrier 55 is pivoted, at 59, the lug 60. This lug is in the form of abellcrank and to the free end' thereof, is pivoted at 61, ,the'link62which is in turn pivoted at 62 to "a second link 63, pivotally connectedat 64 to the cross bar 58; The links 62 and 63 are provided withregistering openings through which may be inserted the shackle shackle26 which is shown in Figures 8 and 9 passing through registeringopenings in the links, securing them together in much the of thepadlock. In the form shown, I have 7 preferred to use in this instancethe bolt same manner as has already been described in connection withthe form shown in Figures 1, 2, 3 of the drawings.

While I have shown and described some preferred embodiments of myinvention, 'it

will be understood that it is not to be limited in all the detailsshown,but is capable of modification andvariation withinthe spirit of theinvention and within the scope of the appended claims.
